LOUIS COTE, OF ST. HYAGINTHE, QUEBEC, CANADA.

MACHINE FOR NAiLlNG ONTH E HEELS OF BOOTS AND SHOES.

SPECIFICAI'ION forming part of Letters Patent No. 310,562, dated January .18, 1885.

Application filed September 20, 1884. (X model.)

To all whom it may concern.-

Be it known that I, LoUis (30171 of the city of St. Hyacinthe, in the county of St. Hyacinthe, Province of Quebec, Dominion of Canada, have invented new and useful Improvements in Machines for Nailing on the Heels'of the operator is enabled to adjust the position of the heel upon the sole with greater exactness than when operating with the machine as constructed before my present invention. By my invention an operator can, with less bodily labor and in the same time required by the old machine to nail on two heels, with my improved machine nail on five or six heels, thus making a large saving in the price of the labor to be paid. for this operation, and in large establishments the cost and room. required for, say,three machines, to do the work of one of my improved machines.

The features which form my invention will be hereinafter fully set forth and described.

In the drawings hereunto annexed, similar letters of reference indicate like parts, and Figure l is a front elevation of aboot and shoe heel nailing-on machine in which are enibodied the improvements forming my present invention. Fig. 2 is a side elevation of the machine shown in Fig. 1. Fig. 3 is a plan of that part of the machine which is situated above the line at, Fig. 2. Fig. 4 is ahorizontal section on line :10, Fig. 2. Fig. 5 is a plan of the treadle for operating rapidly the pressenplate or follower-block a. of the machine. Fig. 6 is a diagram showing the manner in which a boot or shoe is held by the machine shown in Figs. 1 and 2 while the nailing of the heel to the sole is accomplished. 7

As in the machine shown in the drawings a considerable portion of it is old, it becomes necessary for the clear understanding of my invention to enter at some length into a particular description of the parts that are old as well as those that are now, also into a general description of how the machine has been heretofore operated.

Letter A is a lower frame, which is firmly attached on the floor, &c., in the ordinary manner. To this is attached the upper frame, B.

On the frame B is secured, by bolts and nuts 0, a standard, D, within which a plunger, E, and rod, F, are situated, as shown in Fig. 6. The standard is provided with a head, G, having within it vertical or nearly vertical holes H, situated in the positions in which the nails are required to pass through the sole I into the heel K. The plunger E is provided with fork projections L, one for each of the holes H, in which they freely slide, so that when the plunger and projections L are moved downward (from the position they are shown in Fig. 6) a sufficient amount of the nails M may be placed in the holes H.

As shown in Fig. 6, the plunger E is in a midway position,showing a nail, M, in a partly-driven condition, or as if the plunger had risen from about the level of the line as, and when the plunger has risen to within a short distance of touching the head G the nail will have been completely driven home into the sole and heel.

a is a presser-plate or follower-block, which is brought down with considerable force upon the heel K, and tightly holds the sole and heel upon the head G while the nails are being driven.

are held that no further explanation is required in this respect.

The rod F extends below the standard 1), as shown in Fig. 1, and is operatedl by the following mechanism: To the under side of the frame B are attached two brackets, b, in which which is journaled a revolving shaft, 0, pro vided with a disk, (I, at its front end. Upon this disk projects a crank-pin, e, which operates a pitman, f. The end of the pitman does not come in contact with the end of the rod F; but whenever it is desired to operate the rod F asliding blockisinterposed between the end of the rod F and the end of the pitmanf, the said block being of such thickness that the desired portion of the stroke of the pitman will be imparted to the rod F. This said sliding block is operated by the handle a. On the shaft 0 is secured agear-wheel, g, which intermeshes with a pinion, h, secured on the driving'shaft 'i, carried, journaled, and revolving in lugs it, formed on the frame A.

Z is a fly-wheel secured on the shaft i, and

Fig. 6 so clearly shows how the sole and heel V m are ordinary pulleys for the transmission of power bya belt in the ordinary way to revolve the shaft *6.

Now, all that has been hereinabove described is old or substantially old, and'the above description is given for the purpose of conveying a clear knowledgeof the state of the machine at the time of myinvention, and to complete the description of what is old.

The object of my invention is to provide the machine with a means of rapidly operating the follower-block a, and, further, that such means shall be automatic in so far as the raising of the follower-block a is concerned after the operation of nailing the sole and heel together has been accomplished.

a is a socket or guide in which moves a slide-bar, I), provided with any suitable feather or key for keeping the slide-bar from turning around, while it is free to slide up and down within the socket or guide a. On the lower end of the slide-bar a head, 0, is formed, and, as shown in Fig. 1, to the lower side of this head the follower-block or presser-plate a is secured by a dovetail recess in the head 0 and corresponding dovetail projection on the follower-block or presser-plate a. On the upper extremity of the slide-bar b a double eye, d,is-

formed, and 011 the socket a an upwardly-extending arm, 0, is formed. This terminates in a horizontal eye, f, through which the screwed neck of a double eye, 9, passes.

h are jam-nuts, for securing the double eye 9 in position, and for adjusting the height of the same. Between the double eyes d and g a toggle-joint, z" 'i, is attached, in the ordinary way, so that by the adjustment of the height of the double eye 9 that of the togglejoint i, slide-bar I), head 0, and followerblock care also adjusted to give the proper distance between the follower --block (a and head G for properly compressing the sole and heel between them when the togglejoint is in (or nearly in) its most extended position. The frame B is provided with upward and backward extending arms B, which unite together at their upper extremity, and to them is secured a double eye, 7c, between which and the center-pin Z of the toggle-joint z" i is attached the toggle-joint m m. (See Fig. 2.) Again, to the center-pin n of the toggle-joint m m is attached the double eye 0, formed upon the upper end of the connecting-rod p, which said connecting-rod passes down through the open space in the frame B, as will be clearly understood by reference to Figs. 2 and 4. The lower end of the connecting-rod is also provided with a double eye, g, which connects in the ordinary way with the treadle-bar a of a treadle, B, of which b is the foot-plate. The bar a is made in one with a sleeve, 0, which is placed and pivoted on ashaft, (i carried in brackets 6, one of which is attached at the back on each side of the frame A. The said sleeve 0 is also provided with a second arm, f upon which is secured a counterbalanceweight, 9

7b2 is an adjustable eontrivance by which the descent of the counterbalance-weight 9 may be governed at pleasure.

The contrivance IL2 is only one modification of a great number that may be applied to the counterbalance-weight or to the arm f 2 upon which it is secured, and as such contrivances are well known and understood it is considered unnecessary to enter into any description of them.

The adjustable contrivance h is not neces sary, although very convenient and suitable, because the descent of the counterbalanceweight 9 would be limited by the head c be ing drawn up so high that it would bear against the under side of the socket a, and to prevent the jar which would be caused to the machine if this were done with force when the machine is working quickly at full stroke, an elastic washer, h, is provided. This is slipped over the slide bar, b, before it is put in place in the socket or guide a.

The operation of the machine is as follows: The counterbalance-weight having raised the treadle B, connecting-rod p, and moved the togglejoints m m and i z" to the positions indicated by dotted lines, thus causing the slide-bar I), head 0, and presser-plate or follower-block to be raised the amount of the distance between the lines 1 and 2, thus giving room for a boot and heel to be placed on the head G, in the position shown in Fig. 6. The holes H are then provided with nails, and the boot or shoe and heel placed in position on the head G, whereupon the foot of the operator is placed upon the foot-plate b and the preponderance of weight of the counterbal ance-weight overcome with sufficient force to bring the follower-block or 'presser-plate a down upon the heel, as shown in Fig. 6, and tightly compress or jack the heel and sole between the head G and follower-block or presser-plate a. The mechanism for driving the nails through the sole and into the heel is then put in motion by actuating the sliding block, hereinbefore mentioned, by the handle 8. As soon as the nails are driven the foot of the operator is removed from the foot-plate I)", and the preponderence of weight of the counterbalance-weight causes the followerblock or presser-plat a to rise by the move ment of the working parts connected to the treadle to the positions shown in dotted lines. The holes H are again provided with nails, ready for the next boot or shoe. By the adjustment of the double eye 9 the height in stroke of the follower-block or presser-plate is adjusted to what is required for properly pressing or jacking any particular thickness of sole and height of heel. This is done by the adjustment of the nuts h.

Although the toggle-joint i 5 is represented. as actuated by a second toggle-joint, m on, yet a bell-crank might be used, because the one arm ofthe bell-crank and the link connecting it to the toggle-joint would be the equivalent of the two parts of the togglejoint m on.

What I claim and wish to secure is as follows:

1. The combination, in a sole and heel nailing machine, of the standard D, provided with plunger E, having projections L, and the rod F, head G, having nail-receiving holes H, said holes also receiving and guiding said projections L, as shown and described, followerjections L, as described, follower block a, slide'bar a, toggle-joints i i and m m, connecting-rod 1), and treadle B, the whole constructed and arranged substantially as shown and described.
